Introducing the SGE 400/3 BB Tactical Gas Mask—originally developed for military and law enforcement use—now available to civilians. This advanced breathing protection device is rated to protect against all CBRN (chemical, biological, radiological, and nuclear)-level threats.

Wearer can be easily identified due to the total transparency of the face-piece

Innovative face seal design allows perfect sealing every time while maintaining an exceptional degree of comfort

Three individual NATO 40mm DIN 3283 filter ports for breathing protection in accordance with EN 136:1998 CL 3 (left and right side port option allows for a more comfortable gun aiming position)

Effectively removes over 99.97% of poison gases, harmful vapors and radioactive solid particles from inhaled air when accompanied with a Multipurpose 40mm Standard A2B2E2K2P3/RD Threaded Filter

Advanced technopolymer created for aeronautical and aerospace requirements is easy to decontaminate an unlimited number of times without deterioration

Manufactured in Italy under strict adherence to International Organization for Standardization (ISO) regulations

Assembled in the USA

Customize your SGE 400/3 BB Tactical Gas Mask to include optional accessories that increase your personal protection factor. Add the built-in drinking system with canteen kit to provide you with a protected drinking source, upgrade to the integrated hood to protect your head neck and shoulders, or add the special lens frame adapter if you wear prescription eyewear.

Make sure your drinking water is safe and free of nuclear, biological or chemical contaminants with the N/B/C Integrated Drinking System Upgrade.

The N/B/C Integrated Drinking System w/ Military-Grade Canteen includes an easy-to-install drinking port in place of the bottom cap on the SGE 400/3 BB Tactical Gas Mask. The specialized tube is supplied with a safety valve that is automatically closed when not in use.

Not sure if you will need extra A2B2E2K2P3/RD Threaded Filters?

Each A2B2E2K2P3/RD Threaded Filter is estimated to protect an average of eight hours. Individual filter life cycle will vary depending on real-world conditions.

Originally developed for military, law enforcement, and civil defense applications, the SGE 400/3 BB is now commercially available for use in personal defense. Its game-changing introduction has created a whole new generation of “advanced” breathing protection devices the world over.

Heavy-Duty One Piece Visor Face Shield

The SGE 400/3 BB is constructed using a highly-durable polycarbonate visor face shield that protects not only the eyes, but the entire face as well. This innovative design feature guarantees an unsurpassed level of cut resistance and impact protection for the face while very comfortably supporting the head harness, valves, filters, regulators and optional equipment upgrades.

The specially-treated polycarbonate material is easy to clean and decontaminate an unlimited number of times. No deterioration has been observed using all normal decontamination methods, including immersion into boiling water.

CBRN-Rated Integral Face Seal

Traditional gas masks consist of a flimsy rubber body fitted with two sealed eye pieces. Since the rubber body must support the weight of any accessories attached to the mask, it must be made rigid and thick (i.e., heavy and uncomfortable). The tensile stress exerted by the ends of the straps is discharged only onto the points where they join the mask body. It is therefore necessary to pull the straps very tightly in order to secure a uniform seal around the edge of the mask. This cumbersome design causes unnecessary discomfort to the wearer’s face.

The SGE 400/3 BB face seal is made of very soft rubber with a supple, bellows-type structure. This unique shape allows for a perfect seal every time without sacrificing comfort. The face seal has a seat into which the edge of the load-bearing face piece is inserted, and the coupling of these two parts is ensured by the fixing rim.

As a whole, the universal fit adjustable head harness, integral face seal and stiff polycarbonate body of the mask together provide far more comfort than traditional masks could ever offer. The SGE 400/3 BB may be worn comfortably for up to five continuous days.

Extremely Durable Filter Port Fittings

The SGE masks have a threaded fitting for application of standard filters (DIN 3183, UNI EN 148-1). The fitting is contained in a single unit which also comprises the exhalation valve. The shape of the internal ring nut allows perfect ventilation of the whole face-piece, preventing misting even at low temperatures.

Mechanical Characteristics

The material used is black polyarilamide, which was originally created for aeronautical and aerospace requirements.

In addition to very high impact resistance, it is not affected by aging or atmospheric factors. Its abrasion resistance is such that after testing with over 3000 assembly/disassembly operations, the filter had sustained no wear.

As already seen, the exhalation valve is fitted onto the same unit containing the filter fitting. Externally the valve has a structure which, although it covers the whole membrane, still allows easy discharging of the exhaled air. The purpose of this covering structure is to keep a sufficient volume of uncontaminated air in continuous contact with the membrane.

The exhalation membrane has been made to require minimum effort even at very high flow rates. The excellent memory of the membranes has been achieved by a combination of innovative design and high grade material. A considerable increase in resistance to chemical agents, has been achieved, using blends containing butyl rubbers instead of the traditional natural rubber used by other manufacturers.

The SGE 400/3 BB Tactical Gas Mask is impervious to aggressive agents due to its special polysiloxane resin coating. Even after very long exposure times of up to 50 consecutive hours, mustard gas failed to penetrate test specimens.

The visor face shield protects not only the eyes, but the whole face against fragments, stones, and splinters caused by explosions. The face shield is left undamaged (i.e., break or perforation) by a steel sphere .25 caliber (6.35 mm) bullet hitting the mask at any point at the speed of 500 feet per second. Blast effects do not impair the protection performances as all the membranes are able to withstand significant pressure.

The SGE 400/3 BB Tactical Gas Mask may be comfortably worn for up to five consecutive days. The Universal Fit Adjustable Head Harness is a headpiece with six straps that adjusts to fit all face shapes and sizes.

The mask design makes decontamination and cleaning easy. In fact, even when rubber is made of mixtures capable of providing a chemical shield, its structure does absorb and is penetrated by the contaminants. The SGE masks are made of two main parts: face shield and face seal. So the majority of the mask is made of plastic materials which are not permeable to aggressive agents and are not penetrated by them even after very long exposure times. It is advisable to clean the mask each time after use. This is easily accomplished by washing with soap and warm water. Hot water can also be used. The mask can be disinfected using non aggressive disinfectants or by immersing it briefly in boiling water.

Maintenance

At least once a year the inhalation and exhalation membranes must be checked, as well as the sealing gasket of the fitting on the mask.
